Kings of Leon cancel U.S. tour

After cutting one concert short in Dallas on Friday and postponing another in Houston on Saturday, Nashville rockers Kings of Leon have cancelled the remaining 25 dates of their U.S. tour. A statement released by the band cites frontman Caleb Followill's "vocal issues and exhaustion" as the reason, and says that the band will not be able to reschedule the U.S. dates due to their international tour schedule.

On Friday, July 29, the band had played 11 songs at Dexa Energy Pavillion in Dallas, Texas when Caleb made an announcement.

"I'm gonna go backstage for a second," he said. "I'm gonna vomit. I'm gonna drink a beer. Then I'm gonna come back out, and I'm gonna play three more songs."

Followill never returned to the stage that evening. Instead, his bandmates Jared and Matthew Followill returned to tell the audience that the concert was over.

Posts on Jared's Twitter account over the weekend suggests that the band was dealing with issues beyond dehydration behind the scenes.

"There are internal sicknesses & problems that have needed to be addressed," Jared wrote Friday night. The following morning, he added, "I know you guys aren't stupid. I can't lie. There are problems in our band bigger than not drinking enough Gatorade."
